The untold story of Britain's cross-dressing high society painter. Gluck was one of the British Establishment's go-to portrait painters of the 1930s. Her shows were attended by royalty, aristocrats and celebrities. She also dressed as a man and called her exhibitions 'one-man shows'. Her lovers were all women, including flower arranger to the stars Constance Spry, and Edith Heald, the ex-mistress of WB Yeats.
